Peridot is a gem-quality Olivine. The name "Peridot" is believed to have originated from the Arabic word faridat, meaning "gem", or alternatively, as the Oxford English Dictionary suggests, it came from classical Latin pæderot - a kind of opal.

Peridot is one of the few gemstones that occur in only one color, an olive green. Radiant green shine of Peridot does not change in artificial light. Found in lava, meteorites, deep in the earth.
